Just some speculation:

The article on AlphaGo Zero is in NATURE.
Perhaps they made the AlphaZero research simultaneously,
and when facing problems with acceptance in a journal (like NATURE)
they decided to publish a preversion on AlphaZero in arXiv.
So, perhaps the 40-block 40-day experiment was not yet done when
they had written the AlphaZero paper.

Just speculating...
